Mapal Green Cleaning Australian Wastewater Pools

Mapal Green Energy seals deal to supply aeration recycling system to Schweppes Down Under for Wastewater Pool Purification

Mapal will work with a local engineering firm to design an aeration system for installation at bottling plants belonging to Schweppes, which has a huge operation across Australia. Mapal will supply the equipment and operate the water purification equipment it installs.

In a Mapal system, bubbles – water infused with air – are used to clean water as part of aeration systems, removing pollutants and separating sludge from water. The treatment removes nearly all the solid waste and pollutants, allowing water providers to purify and recycle water quickly and efficiently.

Among water professionals, bubbles are considered one of the more effective ways of treating sewage and water suffering from industrial pollution. But bubble purification systems haven’t been popular because they are generally limited to use in smaller, manmade pools and lagoons.

In a bubble purification system, a machine pumps oxygen into wastewater to enhance “aerobic digestion,” a bacterial process occurring in the presence of oxygen, in which bacteria consume organic matter and convert it into carbon dioxide, which is them released into the atmosphere.

But traditional aeration systems have limitations. In order to get the bubbles to all parts of the wastewater, water utilities have relied on mechanical aeration (large machines that are stationary or mobile that make bubbles by agitating the water) or jet aeration (jets pushing air into the water). Both are expensive to run, requiring large amounts of energy to diffuse the air into the water; in addition, jet aeration, while a little cheaper, is suitable only for small concrete-lined pools or lagoons.

Mapal’s system solves all these problems, according to company CEO Ze’ev Fisher. Mapal’s idea is to use floating aerators that “travel” across the surface of the water, diffusing oxygen throughout the pool (up to a depth of six meters). Unlike with floating mechanical diffusers, the Mapal version has a series of tubes that extend into the water, requiring far less energy to push the oxygen into the lower depths of the water and ensuring that the oxygen gets to all parts of the wastewater.

Mapal’s water purification system has already made a huge splash in the UK, where the company’s technology is used to clean up the water for three water companies – United Utilities, the UK’s largest listed water company, as well as Anglian Water and Thames Water, two large water suppliers in southern England. Mapal has been accepted as a member of British Water, the UK’s leading trade body.

According to CEO Zeev Fischer, Mapal’s technology is now being used by large companies in Israel and abroad, including South Africa, Brazil, Angola – and now Australia.

“We have a well proven technology in use at over 40 sites around the world, including in the pulp and paper sector and by leading utility companies in the UK, where regulatory pressure has long been a feature of the industry,” he said. “The technology is perfectly suited to the new challenges laid down in the latest EU BAT-AEL rules and our in-house teams can advise on all aspects of systems design and installation.”
